The best concert I've had

The best concert I've had attend it's the only one too (until now).
It was a concert of a Korean boy group that I listen a lot.  The name of the band is Seventeen. They are 13 boys in a group! It's the largest number of members in a Korean group until now. They are divided into sub-units in accordance with the specialty of each member. So there are 3 sub-units: Hip-Hop, Vocal, Dance. They are so adorable and happy, and unlike other Korean bands the write and produce every song.
The concert was on Movistar Arena on August 29th, the last year, and it was sooooo good.
I have to say it, attend wasn't easy, I spent all my savings to pay the tickets for me and my sister. I walked a lot searching for the tickets too because they were sold out in many of the points of sales. I was 11 hours outside Movistar Arena, and I was studying! because I had to take a test the next day.
I think I have never run so fast, we were 11 hours outside so when the staff opened the doors we were just interested in find a good place to see Seventeen. When we were in I was so excited, everyone was singing the songs (because the staff put some videos when we were waiting) with a big smile on their faces even when the concert hadn't started. I don't know how to describe how the atmosphere was... it was just incredible, everyone was so so happy, jamming every song and screaming with all they had, that it feels really good.
I'm a big fan of k-pop and I had the opportunity to go with my sister and one of my best friends, that's why I think I enjoyed so much.
 I arrived my house at 3 am, and I was dead, I had no voice.
PD: I approved the test if you are thinking about this:D
